Abstract
A promising afterschool intervention to increase health knowledge and influence choices to reduce risks related to type II diabetes in school-aged, low-income, African American youth is described. Researchers used a community-based program called CASTLES (Communities and Students Together for Learning Enhanced Service). Repeated measures were used to test the effect of the afterschool program on exercise and nutrition. Forty-six children participated in this free program. Significant results demonstrated decreased consumption of sugar-sweetened beverages and screen time and increased exercise and health knowledge. Communities interested in influencing behaviors related to childhood obesity should develop strong community-based programs, such as the CASTLES model, incorporating nutrition information and structured physical activity.
